Moisture Lock 101 is a chemical floor hardener designed for porous, cementitious substrates to harden, seal and dust-proof surfaces and help reduce moisture vapor transmission (MVT).
As a clear, water-based liquid, Moisture Lock 101 penetrates and reacts with the free lime and calcium carbonate in concrete to fill and seal pores and capillaries.
Coverage:100-300 sf/gal
This easy-to-use, pre-mixed formula hardens and seals the substrate, blocking MVT and maximizing the coverage of NAC primers to ensure a permanent bond to the substrate.
